So you want to be a dragon trainer do you? Prepare yourself for adventure, excitement and training as Hiccup, Astrid, Toothless and Gobber tell the legend behind the Book of Dragons and reveal insider training secrets about new, never-before-seen dragons.
A cute short film that's probably a great supplement for serious fans of the franchise-lore, but offers little for casual or non-fans.
_Final rating:★★ - Definitely not for me, but I sort of get the appeal._
